COIN-CONTROLLED VENDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 762,044, dated June '7, 1904.

Application filed June 13, 1902. Serial No. 111,471. (No model.)

To add w/tom it may concern.-

' Be it known that we, WILLIAM H. GARLAND and J AMES P. LOMBARD, citizens of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Coin -Controlled Vending -Machines, of which the following is a specification.

Our invention relates to coincontrolled vending-machines; and our object is to produce a machine of this character which operates reliably, can be manufactured at a low cost, and is of simple, strong, durable, and compact construction.

To this end the invention consists in certain novel and peculiar features of construction and combinations of parts, as hereinafter described and claimed, and in order that the invention may be fully-understood reference is to be had to the accompanying drawings, in which i Figure 1 represents a section taken on the line I I of Fig. 2. Fig. 2 is a horizontal section taken through the casing and showing therein a pair of coin-operated mechanisms, one in plan view and the other in section, the section occurring on the line II II of Fig. 1. Fig. 3 is a sectional view of coin-operated mechanism similar to that of Fig. 2, but showing the push-bar as locked from complete in' Ward movement when no coin hasbeen dropped into the machine. Fig. i is a similar view showing the arrangement of the parts affected by the introduction of the proper coin. Fig. 5 is an inverted plan view of one of the slides- Fig. 6 is a vertical section taken through one of the slides and through the package-magazine and showing the lipped block as looking said slide in such position that a coin cannot be dropped into the machine. Fig. 7 is a horizontal section taken just above the rack-bar and short arms depending from the spring-pressed coin-holders, said figure showing said coin-holders as spread apart to effect the release of the coin. Fig. 8 is a vertical section taken on the line VIII VIII of Fig. 6,,the lipped locking-block being omitted. I-ig. 9 is a horizontal section taken below the like sectionrepresented by Fig. 2 and showing the means for preventing ery-opening 2 near its lower end and a tray or drawer 3 at a convenient point above said opening.

4 designates the cover for the front portion of the casing, having coin-slots 5 and openings 6, corresponding in number to the inde- 5 pendent mechanisms contained in the casing. As such mechanisms are precisely alike, the description is in the singular.

A rectangular frame is supported in any suitable manner between the cover and the 7 tray or drawer 3 and consists of parallel front and rear bars 7 8 and the end bars 9. The upper edge of the rear bar 8 is notched, as at 10, and connecting said bar at opposite sides of said notches with bar 7 are parallel bars 11, the opposite edges of said bars and the inner edges of the end bars 9 being grooved, as at 12, to form a track for the slides, hereinafter described. It isto be understood that there are as many notches 10 as slides em- .ployed and'that while the machine may be made with only a single slide and notch it is customary and preferable to build it with a plurality of each.

13 designates a bar connecting the lower 5 edges of the end bars 9 in any suitable manner and provided centrally between each pair of bars 1'1 and the ends 9'with a rearwardlydisposed rack 14.

15.designates a bar bolted to the lower side 9 of front bar 7, so as to form a support for the dogs 16, pivoted to and between said bar 15 and bar 7, said dogs projecting inward and having at their inner sides forwardly-disposed teeth '17 for a purpose which hereinafter appears and forward of said teeth andin a higher plane with cam-lugs 18, the dogs being held yieldingly toward each other by means of the retractile spring 19.

The portion of the mechanism above described moves neither forward nor backward, the rack forming a lock against improper movement of the coin and the dogs against inopportune movementof the push-bar 20, the same being mounted slidingly in bar 7 centrally of but above said dogs and terminating at its rear end in a finger 21. At a suitable point the push-bar carries rigidly a depending arm 22, having in itsrear edge a pair of notches 23 for engagement with the teeth 17 of the dogs in case the proper coin has not first been deposited in the machine. (See Figs. 3 and 9.) At its lower end arm 22 is provided with laterally projecting branch arms 24, carrying guide-rods 25, which at their rear ends extend slidingly through openings in the rear bar 8, expansive springs 26 being sleeved on said rods and bearing at their opposite ends against said bar and said arms, so as to normally hold the push-bar in the position shown in Figs. 1 and 2. In order to arrest inward or rearward movement of the push-bar, arm 22 carries a stop-screw 27 to engage the front end of rack 14, said stop-screw having a lock-nut 28 to prevent its rotation.

29 designates a slide fitting in grooves 12, hereinbefore mentioned, and provided with a slot 30, registering with coin-slot5 and with a pair of vertically-depending arms at the front and rear margins of said slot, the rearmost arm 31 being provided with a hole 32 in alinement with and of slightly greater diameter than the push-bar. The other arm (numbered 33) by preference is bifurcated, so as to permit the push-bar to slide through the same. Near its front end the slide is provided with depending lugs 34, having their outer sides rounded, which lugs normally occupy the position shown in Figs. 2 and 3-that is, against the rear or inner side of bar 7 and the inward projection 7 thereof. Near its opposite end the slide is provided with an opening 35, having a forwardly-projecting tongue 36 at its rear edge, and at opposite sides of said opening are a pair of depending ribs 37, in which is secured a pivot-rod 38 for a gravity-dog, consisting of a pair of arms 39, connected at their front ends by a weight 40 and terminating at their rear ends in shoulders 41, and arms 42, projecting rearward] y from the lower ends of the shoulders, which under ordinary conditions are held by the weight up against the bottom of the slide, so that the shoulders are projected above the latter and in position to engage the undermost package a of the vertical series mounted in the magazine 43, supported in the upper portion of the casing, as shown, or in any other suitable or preferred manner. the weight of said packages being borne by the slide which forms a movable bottom for the magazine. provided with an opening 44in its front side, through which the dog operates to expel a package, and with an opening 45 in its rear side, through which the package is expelled, a flange 46 of the magazine serving as aguard to hold the expelled package upon the slide until the time of delivery arrives.

The mechanism for gaging the character of coin by which the deliverance of a package may be effected, for supporting the coin in operative position,and for locking the coin and pushbar against return movement after once being forced rearward a slight distance is constructed as follows: 47 designates a pair of horizontal bars at opposite sides of arms 31 33 and pivoted to bosses 48, depending from the slide, the rear ends of said arms being connected bya retractile spring 49 to hold them with their vertical grooves 50 in register with the sides of the slot 30,set-screws 51 being mounted in said pivoted bars, so as'to project slightly into said slot until their points are a distance apart almost imperceptibly less than the diameter of the coin designed to operate the machine, so as to gage and hold said coin when dropped through from the coin-slot above. The screws are also so disposed that only a certain coin will operate the machine, as a token slightly thinner will pass on through the slot at one side or the other of said points. A coin of larger diam eter or of greater thickness than that with which the machine is intended to operate is excluded from the machine by having the coinslot 5 to-correspond almost precisely with the diameter and thickness of the proper coin. The distance between arms 31 33 preferably will be almost twice the thickness of the coin in order that a disk of less thickness may pass to one side or the other of the gage-points.

Assuming that the parts are in the position shown most clearly in Figs. 1 and 2 and that a coin of the proper denomination has been inserted through the coin-slot and is supported by the gage-points between arms 31 33, as shown in Figs. 4 and 8, inward or rearward movement of the push-bar will cause its finger 21 to bear against the coin. As a result the push-bar and slide are locked and move together, the rounded sides of lugs 34 by engagement with cam-lugs 18 forcing dogs 16 apart against the resistance-of springs 19 (see Figs. 2 to 4, inclusive) to enable the pushbar arm 22 to pass the teeth of said dogs, the lugs 34 afterward passing said teeth because they operate in different horizontal planes. Immediately after the push-bar and slide thus begin their synchronous inward movement the shoulders of the dog carried by the slide engage the undermost package a and cause it to move rearwardly also, su ch movement continuing until the parts occupy the position shown by dotted lines, Fig. 1, where it will be noticed that the coin is inward of the rack 14 and the package rearward of the magazine,

The magazine is and in this connection it will also be observed that as soon as the package is forced beyond the packages in the magazine the weight of such packages overcomes the resistance of the weighted dog and depresses the same to the plane of the slide, as also shown by dotted lines, said figure. The push-bar being released, the compressed springs 26 return it and the slide to position, as shown in full lines, Fig. 1. As this return movement begins the lost motion between the push-bar and the slide, corresponding to the distance between the coin and the push-bar before the latter is moved, enables the former to be moved a sufficient distance to permit the coin to drop into tray or drawer 3 before the push-bar by the pressure of its bar 22 on lugs 34: imparts corresponding movement to the slide, the latter delivering the package in such return movement by sliding from under it, as will be readily understood by reference to Fig. 1, the weighted dog being held depressed in such return movement until it clears the front edge of the series of packages, when it swings automatically to its original position, as shown in full lines, Fig. 1. An attempt to defraud the machine by utilizing the same coin to effect the deliverance of more than one package is prevented, because the arms 47, tapered at the front ends, (see Fig. 7,) depending from bars 47, come in contact with and are forced apart by the tapered front end of the rack-bar shortly after the coin begins to move-that is, immediately after the coin passes the foremost tooth of said rack-bar. This movement apart of said bars permits the coin to drop upon the rackbar without withdrawing from the path of the push-bar, the pressure of the latter causing the coin to ride successively over the rack-bar teeth until it is eventually dropped beyond them. WVhen the pressure is removed from the push-bar at any time after the coin has passed the first shoulder of therack-bar, such coin by impingement against the first square tooth face presented will lock the push-bar and slide against outward or return movement. It will be furthermore observed that the machine cannot be operated a second time even if a string be attachedto the coin, because the slide completely bridges the coinslot, fitting so closely against the top or cover that it could not be operated with the cord through the slot unless in such operation the cord should be cut, which would invariably be the case. Again, it will be obvious that the machine cannot be operated to deliver a package without a coin and that the push-bar can be-moved but a slight distance unless a coin is in place, the latter fact tending to discourage the attempts of children to amuse themselves by operating the push-bars. In such attempt the push-bar and slide are not locked together unless a coin is used. As a consequence there is nothing to force dogs 16 apart, and their teeth 17 occupy the path of and enter the notches or recesses 23 of the push-bar arm 22, thus preventing complete inward movement of the latter, as will be readily seen by reference to Figs. 3 and 9. When the last package has been delivered, the slide is automatically locked with its slot 30 slightly inward of and out of register with the coin-slot 5, so as to prevent another coin being deposited in the machine. This object is effected by means of a lipped bloc r 52 upon the topmost package and adapted to slide downward in themagazine with such package. Said block 52 projects forwardly beyond the vendable packages and is provided with a depending lip 53 to project through slide-opening 35 forward of tongue 36 of the latter, and thus lock the slide in an inoperative position, as shown clearly in Fig. 6.

Having thus described the invention, what we claim as new, and desire to secure by Letters Patent, is

1. The combination of acoin-carrying slide, a push-bar movable independently of the slide for a slight distance when the latter carries no coin, one or more spring-actuated dogs in the path of said bar, and means movable with the slide for throwing said dog or dogs out of the path of the push-bar when the slide carries a coin.

2. The combination of a coin-carrying slide, a push-bar, means for locking the push-bar against operative movement when the slide carries no coin, and means movable with the slide for releasing the push-bar for operative movement when the slide carries a coin.

3. The combination of a coin-carrying slide, a push-bar movable with and initially independent of the push-bar, a dog or dogs in the path of the push-bar, and a lug or lugs depending from the slide and adapted as the latter is moved by the engagementof the pushbar with the coin, to trip said dog or dogs out of the path of the push-bar;

4:. The combination of a coin-carrying slide, a push-bar to engage the coin and advance the slide, a rack, and means to permit the coin to descend in the slide and rest upon the rack so as to lock the slide from return movement while the coin is upon the rack.

5. The combination of aeoin-carrying slide, a push-bar to advance the slide by impingement against the coin, a rack, means, as the slide disposes the coin beyond the foremost tooth of the rack, to permit such coin to slide downward and rest upon the rack, and means, after the slide has been moved sufficiently to dispose the coin beyond the opposite end of rack, to release the coin by successively start ing the push-bar and slide on their return movement in the order named.

6. The combination of a slide equipped with a coin support and gage, a push-bar to advance the slide by engagement with the coin, a rack, and means to trip the supportand gage and permit the coin to rest uponthe rack after the foremost tooth of the latter is passed, means after the coin has dropped beyond the rear end of the rack for returning the pushbar and slide to their original positions, and means for restoring the coin support and gage to its original position.

7 The combination of a coin-slot, aslide to receive the coin from the slot, a support and gage to hold the coin in the slide, a rack, a push-bar to impinge on the coin and thereby move-the slide, and means to trip the support and gage and permit the coin to rest upon said rack after the foremost tooth of the latter is passed.

8. The combination of a slide, a coin support and gage carried thereby and embodying a pair of arms pressed yieldingly toward each other and provided with adjustable points to WILLIAM H. GARLAND. JAMES P. LOMBARD.
